    GRBL Connecting Arduino UNO TB6560 Driver

    Hi,

    Hope this hasn't been asked elsewhere on this forum. I have searched, but my searching skills may not be up to par.

    I'm trying to work out the connections between an Arduino UNO R3 running GRBL to a TB6560 stepper driver, specifically this one:

    TB6560 Single Axis 3A Stepper Motor Driver - Green (10~35V)

    The GRBL firmware has these outputs:

    - Spindle Direction
    - Spindle Enable
    - Limit Z
    - Limit Y
    - Limit X
    - Stepper Enable / Disable
    - Direction Z
    - Direction Y
    - Direction X
    - Step pulse Z
    - Step pulse Y
    - Step pulse X

    The Stepper Driver has :

    - EN +
    - EN -
    - CW -
    - CW +
    - CLK -
    - CLK +

    I've got the motors hooked up on the other end, just cant work out these connections.

    Any help would be greatly appreciated.

    Re: GRBL Connecting Arduino UNO TB6560 Driver

    There are at least a couple ways to hook it up, but this should work:

    - EN + Stepper Enable / Disable
    - EN - Ground
    - CW - Ground
    - CW + Direction X (if you're using this driver for the X axis, otherwise choose a different direction axis signal)
    - CLK - Ground
    - CLK + Step pulse X (if you're using this driver for the X axis, otherwise choose a different step pulse axis signal)

    Thanks!

    This helped. Couldn't for the life of me find these connections anywhere.
